Question

The force between two asteroids is 500,000 N. What will the force be if the masses of both asteroids are doubled?

Answer 1

Answer:

New force will be equal to $200000N$  

Explanation:

We have given gravitational force between two asteroids is F = 500000 N

Now let mass of both asteroids are $m_1\ and\ m_2$

And distance between them is R

So force of attraction between them is $F=\frac{Gm_1m_2}{R^2}$

Now according to question mass of both the asteroids are doubled

So new force of attraction $F_{new}=\frac{G2m_12m_2}{R^2}=4F=4\times 50000=200000N$
